Compared with other compounds in its class, the molecular weight of 473.98 g/mol gives Pazopanib Hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Pazopanib Hydrochloride (CAS 635702-64-6) is a high-purity analytical reference standard with the molecular formula C21H23N7O2SHCl and a molecular weight of 473.98 g/mol.
Pazopanib Hydrochloride (C21H23N7O2SHCl) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Pazopanib Hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
